Background
Coronavirus disease 2019 (COVID-19) has rapidly reached epidemic proportions internationally and destabilized some of the most robust healthcare systems.
Beyond the emergency of diagnosing COVID-19 cases, it is important to provide solutions to identify and reduce transmission risks in hospitals. It has been shown that SARS-CoV-2, like SARS-CoV-1 in 2003, is characterized by a particularly high rate of hospital-acquired infections. In response to this finding, the Mérieux Foundation, in collaboration with Prof. Philippe Vanhems, an epidemiologist at the Hospices Civils de Lyon (France), has developed a research protocol to assess the risk of nosocomial transmission of SARS-CoV-2: the NOSO-COR project.
Objectives
This is a prospective, non-interventional hospital-based study which aim is to describe and document COVID-19 cases nosocomial transmissions in hospitals and describe hospital infection prevention and control practices and policies.
The main objectives of this project are:
- Conduct a skills mapping in hospitals to identify interventions needed to limit nosocomial infection cases;
- Develop an epidemiological study for a better knowledge of the transmission chains and the impact of infection prevention and control measures in hospitals, in order to identify the determining risk factors for these cases;
- Propose solutions to identify and reduce the risks of transmission in hospitals.
Activities
This study is implemented in the following countries:
- Bangladesh
- Brazil
- Ivory Coast *
- Guinea *
- Lebanon
- Madagascar *
- Mali *
In addition, this protocol is currently being proposed to 8 university hospitals in France, with a view to sharing results and experiences.
The Mérieux Foundation manages the implementation of the research protocol in the countries, particularly in the research laboratories that are members of the GABRIEL network, and the Hospices Civils de Lyon are responsible for the implementation in the French university hospitals. Prof. Jianwey Wang, from the Christophe Mérieux Laboratory in Bejin, acts as scientific advisor.
* in collaboration with Africa CDC and with the support of the Bill & Melinda Gates Foundation
Results
Deploying an international research project in the context of a global health crisis requires long and complex processes. Despite the closure of borders, the lockdown in many countries and the lack of personal protective equipment, it was necessary to launch the protocol before the epidemic gained ground. The teams involved redoubled their efforts and were able to count on the incredible mobilization and support of local partners to sustain the project and ensure its implementation despite the difficult context, as of March 2020.
- The study has been registered on the clinicaltrials.gov website under the identifier NCT04290780.
- The project has been approved by the ethics committee in France and by the national ethics committees of the partner countries.
- Centralized data management has been implemented.
- Most sites are in the final stages of recruitment and are entering the study closure phase, which includes data sharing and preservation.
The NOSO-COR project has also been involved in building capacity in several countries to access COVID-19 diagnostics and to implement clinical research studies.
